Here is you answer mate ✌️✌️✌️

The D' Arsonval gvanometer is a moving coil ammeter . it uses magmatic deflection , where current passing through a coil placed in a magnetic field of a permanent magnet causes the coil to move. .... a moving coil meter indicates

the average (mean) of a varying current through it , which is zero for AC.

hope it's helpful for you mate ✌️✌️✌️✌️✨✨✨✨

⭕️Principle: When a current carrying coil is suspended in a uniform magnetic field it is acted upon by a torque. Under the action of this torque, the coil rotates and the deflection in the coil in a moving coil galvanometer is directly proportional to the current flowing through the coil.

❇️Most of the Moving coil galvanometers, used to measure current (Ammeter), voltage (Voltmeter) or indicator of current in the circuit (galvanometer) are of type “pivoted type moving coil galvanometer”. ... It must admit the current to be measured through it. This is possible only when it is in series in the circuit.
